Answer:
[tex]n=3[/tex]
Step-by-step explanation:
Note that [tex]2^5*5^2=2^3*2^2*5^2=2^3*(2*5)^2=2^3*10^2[/tex].
Aha! We see a path to the solution!
We now know that our equation is actually [tex]2^3*10^2=2^{n}*10^2[/tex].
We can divide both sides by [tex]10^2[/tex] to get [tex]2^3=2^{n}[/tex].
By inspection or taking the logarithm base 2 of both sides, we see that [tex]3=n[/tex].
So, the answer is [tex]\boxed{n=3}[/tex] and we're done!
The population of insects in an experiment has
been increasing by 9% each week. If there were 16
insects at the beginning of the experiment, predict

Note: I got it right on the same test you took as me.
The value of time period for the equation is 8.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The population of insects is increasing by 9% each week = 0.09
At the beginning of the experiment, number of insects = 16
Number of insects increased per week
⇒ [tex]16+16(0.09)[/tex]
Let the time period be x.
Number of insects increased after 8 weeks can be found by the equation,
[tex]Future Amount = 16 (1 + 0.09)^{x}[/tex]
⇒ [tex]Future Amount = 16 (1 + 0.09)^{8}[/tex]
Hence we can conclude that the value of time period for the equation is 8.

The zoo needs to replace some of the railroad tracks that support their train ride. The total length of the track is 500 feet,
and there are three sections that need to be replaced. These sections measure 61, 83, and 63 feet. How much of the zoo
railroad track does not need to be replaced?
Answer:
293 feet.
Step-by-step explanation:
Their track is 500 feet, and there are three sections. Add these sections(61+83+63=207) and subtract from the total(500-207=293)

Give a convincing argument with logical explanations that the contrapositive of a conditional is the
same as the converse of the inverse of the conditional
Answer:
see explanation. (I did this exact assignment this morning, and this is very similar to what I submitted)
Step-by-step explanation:
The contrapositive of a conditional is the same as the converse of the inverse of the conditional.
The best way to prove/support this statement is to create an example. You should start by creating a conditional; you can then form the conditional's converse, inverse, and contrapositive. Here is an example:
Conditional: If C, then D. (starting statement)
Converse: If D, then C. (conditional reversed)
Inverse: If not C, then not D. (opposite of the conditional)
Contrapositive: If not D, then not C. (reversed opposite of the conditional)
Based on the information from the example you gave, you can conclude:
The converse of the inverse: If not D, then not C. (reversed opposite of the conditional)
Because: The converse is the conditional reversed (If D, then C). The inverse of the converse, in this case, would then make it the opposite (If not D, then not C).
I have not yet received a grade on this assignment, but I know the information is correct; the amount of explanation you need to give really depends on how your teacher grades. Personally, I just submitted an example (similar to the one above) that was color-coded to help show the different parts of each statement.
I hope this helps! :)

The rate of change is also known as the slope or rise / run.
Slope Formula: (y2 - y1) / (x2 - x1)
First, we'll need two points that are on the line. You can choose any two points you want, as long as they are on the line.
Point 1 = (0, 1)
Point 2 = (-2, -3)
Then, we'll plug the two points into the formula and solve for the slope.
(-3 - 1) / (-2 - 0)
(-4) / (-2)
2
The rate of change of this line is 2.
Hope this helps!! :)
Answer: the rate of change is 2

Robin works as a customer service representative. She knows that the
amount in dollars of her yearly bonus is represented by the expression - 1.25x + 651, where x is the
number of complaints customers had about her during the year. To find her bonus if she gets 12
complaints, she substitutes 12 for x. What should be her next step? What would her bonus be?
Answer:
multiply -1.25 x 12
Sense a negative and a positive will always be negative when dealing with multiplication you'll get -15
now -15 +651= 636
always take the sign of the biggest number.

15
The fraction 15 is the same as 15 divided by ___
Answer:
If its just 15 then its 1
Step-by-step explanation:
Because 15 divided by 1 is 15 which is the fraction.
Answer:
Below,...!
Step-by-step explanation:
15 is not a fraction as is you can put any number over a one and that whole number immediately becomes a fraction:
[tex]\frac{7}{1} or \frac{43}{1} or \frac{987}{1} or \frac{1}{1} or \frac{15}{1}[/tex]
15/1 is your fraction so 15/1 divided into 15 equals 1
[tex]\frac{15}{1} / 15 = 1/1 = 1[/tex]

Y-k = m(x-h) solve for m
Answer:
Simplifying
y + -1k = m(x + -1h)
Reorder the terms:
-1k + y = m(x + -1h)
Reorder the terms:
-1k + y = m(-1h + x)
-1k + y = (-1h * m + x * m)
-1k + y = (-1hm + mx)
Solving
-1k + y = -1hm + mx
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-1y' to each side of the equation.
-1k + y + -1y = -1hm + mx + -1y
Combine like terms: y + -1y = 0
-1k + 0 = -1hm + mx + -1y
-1k = -1hm + mx + -1y
Divide each side by '-1'.
k = hm + -1mx + y
Simplifying
k = hm + -1mx + y
Step-by-step explanation:
Describe what is meant by the slope of a non-vertical line. Explain how your description relates to the definition of slope.
Answer: A verticle line does not have a slope.
Step-by-step explanation: Slope is the rate of change of y for each change in x. y = 2x is a line with slope of 2. Each time x is incremented by 1, y will increase by twice (2x) that amount. There is no slope to a verticle line, unless you want to call it infinite. The value of y is not defined by x.

CAN SOMEONE HELP ME WITHOUT SENDING LINKS
Answer:
Below.
Step-by-step explanation:
The slope = difference of y values/ difference of x values
13. Slope = (-5-5)/(-3-2)
= -10/-5
= 2.
14. Slope = (-8-8)/(7-9)
= -16/-2
= 8.
